IIvIPRov'la'lvIENTpIN CAR-AxLE BoxEs.

Specification forming part of Letters Patent No. 198,032, dated December 11,1877; application filed october 6, 1817.

To all whom it may concern:

Be ,it known that I, TRENTON W. LILLARD, of L uray, lin the county of Page and State of Virginia, have invented a new and useful Improvement in Gar-Axle Boxes, of which the following is a specification:

Figure 1 is a vertical section of my improved axle-box, taken through the line fr ab, Fig. 2. Fig. 2 is a vertical section of the same, taken through the line y y, Fig. l. Fig. 3 is a top view of the lower half of the same.

Similar letters of reference indicate corresponding parts. A

The object of this invention is'to furnish improved axle-boxes which shall be so constructed as to keep the journals always lubricated, and at the same time remove any grit or dust that might cut or wear the journals, and which shall be simple in construction and convenient in use.

The invention will first be described in connection with the drawing,` and then pointed out in the claims.

A represents the upper part or half of the axle-box, and B- the lower part, which are secured to each other by bolts C. D is the oiltank, which is secured to the lower part B by bolts E.

In the cavity or bearing ofthe upper partA is placed alining, F,ofantifriction metal to receive the wear, and in the face of which are formed inclined grooves to receive the surplus oil from t the journal, and carry it down into the grooves in the surface ofthe lower part B to the wick- Gr, by which it and any grit or dust that may be upon the journal are carried down into the tank D and prevented from reaching the journal. The wick Gr4 is made in the form of an endless band or bands, and passes over a bar, H, which is placed in a recess in the'lower part B, and which is held up by a spring, I, placed beneath it, ,the middle part of which is supported by the drop-loop J, the ends of which are bent outward and rest in recesses in the said part B. The revolution of the journal against the endless wick G causes the latter to pass over the bar.

The spring I holds the wick upagainst the journal as it or the lining F wears, so that the said journal Vmay always be properly lubricated. y l

Any grit or surplus oil lfrom the end parts of thejournal is caught `by and passes down through grooves or passages into the tank D. Therefore the grit is caught before it gets to the journal.

v The tank D is made with a projecting spout, d', for convenienceiu pouring in oil, and the mouth of which is covered with a detachable cover, K. l

recess, in combination with a small bar, H,-

spring I, and loop J, to hold wick, as shown and described.
